Be it known that I, GUSTAV SOHAEFER, a citizen 1 A of the 1 United: I States, residing .1 at

Worces-ter, in the county of Worcester and -State of Massachusettamaveinvented anew juand usefulOlean'er for Garnetting-Machines,

01 whichthe following is a specification.

This inventionrelates to a garnetting ma chine used the prepa'rationiof wool and the like." These 'garnetting machines are provided with cylinders and also with rolls working on said cylinders which have teeth "made up by a1series of rings of steelprovided with notches therein and set out of registration with eachother and -.slightly spacedso as to setthe-teeth slightly apart and permit them-to engage and clean the r wool. .Itis well known in practiceFthat thesenspaces .fill up with oil and dirt and other solid matters with a smallpercentage of fiber therein, butthe fiber is so embedded in theothermaterials that it is hardlytobe i distinguished therefrom; Afterxthe'y get a time consuming operation and seriously 1 interferes with the'use ofthese machmes,

f reducing their'production materially.

to provide a quick and eflicient wayof clean- 5 ingthe; cylinders particularly butalsothe TI'OllS- in a way that will be moreieflic'ient.

ThisI accomplish in a very simple way as will appear. 1 3 4 Referring to the drawings,

It is provided with apulley 22 and is driven'loy belt fromanother pulley on the machine not shownjso that; although it is drivenifromi the power. which drivesthe filled up to a certain extent they have to becleaned; The machine has to be stopped, and the cleaning is -donje by hand.

This done by the usual trolley arrangement usually employd for 3 manipulating the rolls and. not shown. 1

H 1 On this shaft is placed a cylindrical brush 23 which is made up of an ordinary cylinder preferably having 1 a surface formed by winding a strip of card clothingthereon.

It is rotated in such a direction that the Figure 1 an'elevation ofthe main cyl-- inder of aFgarnetting 'mach1ne'i with a preteeth of the card clothing at-(the point of contact with thecylinder' 12 movein a direction-opposite to' that of the rotation of the cylinder, andit isset so that the teeth of the card clothing enter the spaces between the teeth of the cylinder 12 so as to dig out the runningbackwardly rotated at comparatively 5 high speed. I have shown the cylinder 23 a "as extending only part w'ay along the length ofthe' main cylinder'but it could be full .length. 1 However, I have shown it of short lengthg By loosening theset jscrews2 l it I; canbe moved along'to anew position and fixed to the. shaft again for another operation.
